Leonard Nimoy, most famously known for his work as Spock in the Star Trek franchise, is currently residing in the Head Museum in Futurama. By the year 3000, the Star Trek franchise has been made into an illegal, taboo subject due to a religion that was sprung off from the iconic television series and its subsequent movies. The actors themselves blast off into space, leaving only Nimoy behind. He teams with Fry to find his old castmates.
